WIND OW-BLIND FASTENING.

Specification of Letters Patent.

Application filed August 23, 1911.

Patented Feb. 24., 1914. Serial No. 645,644.

T0 all whom it may concern:

Be it known that I, JOHANN J. DANIELS, a subject of the Emperor of Germany, and a resident of New Rochelle, in the county of l/Vestchester and State of New York, have invented certain new and useful Improvements in Window-Blind Fastenings, of which the following is a specification.

The invention relates to improvements in window-blind fastenings, and consists in the novel features, arrangements and combinations of parts hereinafter described, and particularly pointed out in the claims.

The object of my invention is to provide a strong, efficient, easily constructed window-blind fastening adapted to the limited space present between outside window screens and blinds, said fastening to be capable of locking the blind in its closed position or holding it in several partly open positions.

A further object of my invention is to provide a window-blind fastening capable of being correctly and easily adjusted and applied to the blind.

My invention resides in a fastening comprising an arm hinged at one end to a vertical rotary member carried by a bracket secured to the blind, while at its other or free end said arm carries a pin which is adapted to any of a series of metal sockets embedded in the window sill at the outer side of the usual screen, said arm being employed, in the closed position of lthe blind, in connection with a specially constructed and located bracket secured to the blind and adapted at its open upper side to receive said arm and lock the same to the blind while the pin at the outer end of the arm by entering one of the metal sockets embedded in the window sill, becomes locked thereto against any movement tending to push the blind open.

rJlhe present invention embodies certain improvements on the window blind fastener shown and described in Letters Patent of the United States No. 852,654 granted to me on May 7, 1907, and said invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which:

Figure 1 is a horizontal section, partly broken away, through a window frame equipped with a window-blind and blind fastening devices constructed in accordance with and embodying the invention, the blind being indicated by dotted lines in an open position; Fig. 2 is a vertical section through the same on the dotted line 2-2 of Fig. 1; Fig. 3 is an enlarged vert-ical section on the dotted line 8-3 of Fig. 1, through a'portion of the bracket and rotary member carried thereby for supporting the shank end of the securing arm, the latter being partly broken away; Fig. 4 is a vertical section through t-he same about on `the dotted line l--l of Fig. 3; and Fig. 5 is an enlarged vertical sect-ion through a portion of the windowblind on the dotted line 5-5 of Fig. 1.

I n the drawings, 10 designates a window casing or framing of usual or any suitable construction, and 11 the usual blind, which is at the outer side of the'window, suitably secured by hinges 12 in a well-known manner.

My invention relates to means for operating and fastening the window-blind 11, and the means I have designed for this purpose are capable of being confined within limited space permitted between said blind andthe usual outside screen, not shown, and comprise an arm or rod 14e which it at one end secured to the blind 11 and at the other end is bent downwardly to form a hook or pin 15 which is adapted to be placed in engagement with any one of a series of sockets 16 provided in the outer window sill when the blind is opened, and to, in addition, engage the bracket 17 carried by the blind and also one of said sockets when the blind is in its closed position, as shown by full lines in Figs. 1 and 2. Y

Upon the lower portion of the innerside of the blindV 11, near its hinged edge, I secure by means of screws a bracket 1S comprising a plate t0 be placed flat against the blind and having a laterally projecting knob 19, containing a vertical central hole within which is secured a vertical pin 20 extending centrally upward from and preferably being integral with a circular plate 21, within a slot 22 in which I hingedly secure on a pin 23 the shank end of the arm or rod 14.-. The pin 2O is preferably passed upwardly through the vertical hole in the knob 19, the latter constituting a sleeve, and is headed at its Vupper end, as at 24, for the purpose of securing the plate 2l and knob 19 in fixed relation to each other, without interfering with the rotary movement of the plate 21 and pin 20. The slotl 22 in the plate 21 extends upwardly from the lower surface of said'plate and entirely across the same, and at one end said slot has a horizontal upper wall 25, whileat its other end said slot inclined upwardly and outwardly as at 26, whereby the arm or rod 14 may be sustained. in a horizontal position, as shown, or turned upwardly at its free endY to disengage the hook or pin 15 from the socket 16. rIhe shank end of the arm o-r rod 14 will preferably have its sides flattenedv to engage the vertical sides of the slot 22, and when the arm or rod 14 is in about a horizontal position, the outer end of the rod beyond the pivot pin 23willA engage the horizontal wall 25 of the slot 22 and Vserve therewith as a stop to sup port the arm or rod in such position. The rotary movement of the plate Q5 and pin 2O is impartedV to the same from the rod 14 during the manipulation of the latter on the opening and elosingof the window-blind.

Upon the inner face of the window-blind about in line with the bracket 18 and' somewhat adjacent to the hook end of the arm or rod 14 when the latter is parallel with said line, I fasten, by means of screws or otherwise, the bracket 17, which, as shown more clearlyV in Fig. 5, is in one integral piece of metal having a curved face 27 leading downwardly to an open-top recess Q8 adapted to snugly receive transversely the rod or arm 14, the side of said recess 28 facing inwardly or toward the room being formed with an upwardly extending linger 29 to aid in quickly Yguiding the rod or arm 14 to said recess and preventing the escape of the same from said recess by any push or pull which might be directed against the window-blind. I regard the bracket 17 constructed and arranged in the manner shown as of very material advantage and as constituting a portion ofv my invention.

The bracket 17 permits the arm or rod 14 fto ybe freely turned upwardly therefrom when it is desired to open the blind 11 and to be returned thereto when the blind is closedl and it is desired to lock the same against being pulled open from the outside. One very material beneiit of the bracket 17 is that owing to its construction it need not be placed in line with any one of the metal sockets 1G, butmay be conveniently located onthe blind 11 anywhere near where the outer portion of the hook orarm 14 will come when the blind is closed. Window vblinds have heretofore been provided with brackets tovcoperate with a hook secured to the blind for locking the blind in closed posit-ion; as, for illustration, I show in my aforesaid Letters Patent a bracket having a rhole .thereinY to receive the pin atY the outer endl of the arm when said pin is moved downwardly to enter the iirst metal socket inthe window-sill, butv in the con` struction shown in said patent the bracket must be very accurately secured to the window-blind so that when the blind is closed it will have its opening directly over the opening in the first metal socket in the windowsill, so that the pin on the end of the rod or arm may pass through the bracket and into the socket. In my present construction n0 .such line adjustment and location of the bracket 17 is required since the pin or hook port-ion of the arm or rod 14 does not pass through the bracket, but on the contrary the body of said rod or arm passes transversely into the bracket at a point removed from the hook. or pin 15.

The operation of the fastening device constituting my invention will be largely understood from the foregoing description.

lhen the blind 11 is in closed position, the rod or arm 14 will be held to the blind by the bracket 17 and pin 20 and to the window-sill by means of the hook or pin 15 then entered in the rst socket 1G. Then it is desired to open the blind the rod or arm 14 will be turned upwardly on the pivotpin 23 until its free end has escaped from the bracket 17 and socket 1G; thereupon the blind 11 may be opened to any of its several customary positions and secured by the introduction of the hook or pin 15 in any appropriate one of the several sockets 1G. Should it be desired to throw the blind all the way open, the arm or rod 14 should then, after the blind has been opened a short distance, be restored to the bracket 17 so that the same may be conveniently supported and cared for. The pin 20 and plate Q1 enable the rod 14, to be turned on a radial line, as indicated by dotted lines in Fig. 1, and, as aforesaid, the formation of the slot 22 enables the rod or arm to have a limited but adequate hinged movement on the pin or pivot 23.

The fastening devices of my invention are adapted without change for use on windowblinds opening either to the right or to the left, or in other words, on either right or left hand blinds, and this is one feature of advantage sought to be obtained by me. The fastening devices of my invention are simple in construction, extremely durable and easily applied to operative position.

My window-blind fastening devices are applicable to easement windows and the like, and hence it is to be understood that the term window-blind is not employed herein in a narrow technical sense.

lhat I claim as my invention and desire to secure by Letters Patent is:

1. A window-blind fastener for locking the blind in its closed position comprising a securing arm having a locking pin or hook at its free end and at its other end being freely secured to the blind near the hinged edge of the latter, a socket in the windowsill to receive said pin or hook when the blind is in closed position, and a bracket (17) secured to the blind approximately near its free edge having an openstop recess (28) to transversely and snugly receive said arm back from its hook-end when the blind is closed and automatically direct said pin or hook to enter said socket; substantially as set forth.
